You cannot build quality into a product, it must be designed into the product.
I just got rid of a 10 year old Infinity I30 with 140,000 miles on it. The interior of that car looked brand new. No exaggeration. It looked like it was just driven off the showroom floor. After 10 years of insane Texas weather!
Now, show me any American designed vehicle after 10 years of the same Texas weather and take a look at it. I promise you, it will look bad. faded color, cracks in the vinyl, seams pulled apart, seat cushions collapsed, and a malady of other problems will plague American designed cars.
If you use cheaper materials to increase profit margins, then you end up with a cheaper quality vehicle. No other reason to use cheap materials. The American car companies can use the same materials used in that Infinity.
I looked hard at the new Mustang. I wanted to like it. I love the exterior styling of it. But the interior just turned me off. It was/is cheap materials. So I took a look at the new Corvette. Beautiful car. Fast, but again, the interior was assembled from cheap materials. Even the leather used in the bucket seats felt cheap.
So why emphasize the interior? Well, most repairs to the interior of a car are very expensive. Also, there is a greater chance the interior will not be assembled back into the condition it was when it came from the factory. So, I want a car whose interior is made from quality materials. I cannot find an American car which fits the bill.
EDIT: Toad, I know you are pro union, but unions, in general, are doing more damage than good to the ability of America to be a manufacturing country with thier current practices.
